Magnetic Imaging Defectscope (MID) - Casing Inspection Log

Q: Can I used MID to inspect casing corrosion while logging through tubing?

A: Yes, one of the main advantages of MID is to inspect metal loss in both tubing and casing in a single run survey and this eliminates the need for pulling tubing that includes significant cost of work-over rig.

Q: Have you compared MID results with any other common casing inspection logs in the Market?

A: Yes, many of our clients have run several technologies in the same well and finally chose MID due to its preciseness and quality and also the fact that casing inspection with MID doesn’t require pulling out the tubing.

Q: Can I used MID to inspect the 3rd barrier (e.g Surface Casing) which usually located behind tubing, production/Intermediate Casing?

A: Yes, with MID up to 3 barriers of pipes can be inspected individually for corrosion or metal loss.

Q: Does MID work if my tubular are non-magnetic contents such as chrome alloy steel?

A: MID tool containing two sensitive sensors records responses in a wide time range of 0.1–275 ms, These characteristics allows the analysis of non-magnetic chrome alloy steel pipes and detection of corrosion at an early stage.

Q: Does MID work if my tubular are coated?

A: Yes, usually coated materials are non-metallic and MID only inspects metal thicknesses.

Q: Is it a matter what is type of fluid inside wellbore while MID inspects the multi-casings?

A: No, MID works independent of the fluid type in the wellbore as it only scan the metal thicknesses. Even Cement between casings are not affecting MID.

Q: Is MID able to detect corrosion in tubing/casing collars?

A: Yes, the corrosion detection algorithm can be applied to detect corroded collars joints in the first barrier.

Q: Does decentralization of MID tool-string or tubing affect the casing wall thickness calculation?

A: Decentralization of both the tubing and the MID tool is shown in the raw logs as an increase in amplitude but it does not impact on thickness logs.

Q: Does MID work in the event where both tubing and casings are corroded at the same depth interval?

A: Yes, Analysis of the decay pattern in a wide time range can determine metal thickness at various distances from the tool and, thus the individual wall thicknesses of the first and second metal barriers, such as tubing and casing or two casings can be reliably differentiated and calculated.

Spectral Noise Log (SNL) - New Generation of Noise Log


Q: How SNL is different and powerful than other noise logs in market?

A: The method how tools record the real noise parameters, sensitivity of sensors, analysis and visualizing the deliverables are unique aspects of SNL technology that helps reservoir engineers, production engineers and well integrity experts get benefit from SNL. With SNL, the matrix flow, fracture flow and noise through micro-annulus cement channels can be identified. SNL records noise from 8HZ to 60,000HZ.

Q: What is the minimum flow rate SNL has ever detected in Canada?

A: The smallest Leak diagnosed by SNL was as low as few bubbles of gas flew to surface in 10 minutes. We have successfully diagnosed SCVF and GM sources with the rate of Too Small To Measure (TSTM). We also had a challenging case where water was flowing out of surface casing with rate of only 18 drops per minutes and 310kpa build up pressure.

Q: Does SNL tool produce its own noise or use its own sound generator for scanning?

No, SNL tool is absolutely dumb and only listening for surrounding noise using very sensitive hydrophones.

Q: Does SNL capture reservoir flow noise through multiple barriers (like for example, tubing and casing or two casings)?

A: Yes, this was the key point for developing super-sensitive SNL tool.

Q: Does  SNL  capture  and  identify  reservoir  noise  through  the  very  noisy borehole flow?

A: Yes, because borehole flow produces a noise in different frequency range comparing to reservoir flow noise.

Q: Does SNL capture the cross flow or lateral flow behind multiple barriers?

A: Yes, one of the advantages of SNL and application is locating if there is any cross flow or lateral flows behind multiple casing.

Q: Does SNL capture a reservoir noise through non-perforated casing in shut- in wells (for example observers)?

A: Yes. The regional flows of regular intensity produce a measurable noise. It’s normally not audible for a human’s ear but can be captured by SNL tool.

Q: Does well completion matter for SNL readings?

A: Well completion may substantially damp the noise volume from reservoir flow especially if borehole is filled with gas. It also affects a reservoir noise spectrum as different completion elements have different damping factor across the frequency range. But the shape of the spectrum is not seriously disturbed so that one can still clearly see the peaks of reservoir flow noise.

Q: Does SNL provide indication of fluid type in reservoir flow?

A: No. But there is indirect indication of gas flow: it’s higher in volume and extending to higher frequencies.

Q: Does SNL provide the direction of channelling?

A: No. But in many cases there is indirect sign of channelling direction. For example, if the low frequency noise has dropped down at some depth and there is no sign of reservoir noise across then it is very logical that a part of the flow channels up behind casing.

Q: Given a vertically fractured reservoir and horizontal leg intersects fractures so that the inflow zones are captured by conventional PLT – is SNL be of any use?

Yes. SNL will suggest if a given fracture is fed from matrix in well vicinity or not. This is obviously very important for planning workovers and reservoir simulations.

tNavigator - New Generation of Reservoir Dynamic Simulators

Q: Does tNavigator run Thermal models?

A: Yes, tNavigator is a full fledge reservoir dynamic simulator, it supports Thermal, Compositional and Black oil models.

Q: What factors make tNavigator to be different than other simulators?

A: Unlimited Scalability and acceleration, real time 3D visualization and interactivity

Q: Can tNavigator import and run my SAGD models in STARS format?

A: Yes, tNavigator reads models in STARS, E300, E100 and MORE and few other formats

Q: What acceleration should I expect from tNavigator?

A: Depend on the model and hardware you are using, tNavigator can run your models 10-30 times faster

Q: Can tNavigator be installed on Windows and Linux Clusters?

A: Yes, tNavigator can be installed on both Windows and Linux clusters with excellent performance

Q: Shall I pay more if I upgrade my Hardware with more CPU and Cores?

A: No, we don’t charge for extra cores in your Hardware. tNavigator has been designed to use all your hardware capacity and even 100s of cores can be used.
